Want some warmth and definition? This is our Standard Retube Kit for the Gibson GA 40RVT and GA 42RVT Combo Amps. The preamp section includes five ECC83S's with one balanced for the phase inverter in V5. The default power tubes are a matched pair of the JJ 6L6GC's, however you can configure this kit to use the JJ 5881's by clicking on the "Customize" button!
These are cathode bias amps so both the JJ 6L6GC's and JJ 5881's are plug and play.
